'y vThis invention relates to car ui'iloading'dev vices andinore particularly toa device especially adapted for unloading minecars and the like at a dump.

,(5 At the dumpsfof an activev mine,y a great many cars must. be unloaded inthe' course of a single day. These cars being heavily loaded With rubble and other refuse from the mine offer considerable r problem .ini unloading.

'oPrevious unloading devices with which We are familiar havebeen of such character that 7.5 shock of a falling 'load' When the car vvas dumped or to both ofthese shocks. Accordingly, an important object of this invention is rthe provision of adevicebf tliischaracter Where theshoclrsof checking both the forward movement of the car and Vofthe lfalling load are prevented or reduced to suchfa point A further object of the invention isto provide a .device of this character having means whereby the discharged load maybe spread to opposite sides of the" right-of-vvay over which the car is moved, thereby considerably minimizing the laborfnecessary in the sprea ling operation. .s

A still further obj ect'ofr theinventioii is to producey a car unloading device lof this character which is portable and `may be rreadily secured Ain any new p'ositionto which it is moved andY which' embodies structure ena-y bling it to provideitsoWn motive power iii such movements. c. These and other objects. We attain bythe f construction shown in the' accompanyingV drawings,1wherein for tliepurpose of illustration is shown a preferredy embodiment of our invention and wherein j Figure 1fis a side elevation of a car unloading device constructed in accordance with our invention; l i I Figure 2 isa detail sectional view therethrough;

Referring noiv more 'particularly to the dra'ivings,the numeral 10 Ygenerally designates almainframe supported adjacent its opposite ends by trucks 11 and r12; having tracliengaging Wheels 13. @ne of these trucks isswiveled, as indicatedat 14, to facilitate movement of the frame over the right-of-y vWay 15. The frame 10 inclines from end to'` end and at its forwardv or receiving end supports inclinedmain rails 16, the Vlovverfends of which are `provided vvith'rail clampsf1?,k whereby .they maybe secured to the rails of Y the right-ofeway Vto lprovide, continuations thereof over whichV a car 171 moving over the riglit-of-Way may `rise totraclrs 18carried by the platform.

One end of the frame embodies pivoted platfornn, generally`v designated at19, and

comprising rail sections or tipple rails QO'vfor the reception of the Wheels 21': of the car 171 and rigidly connected to'one anothergas in;v

dicated at l22. JThese rail sections'at one end Ahave upwardly `extending arcuateiy curved portions 23 adapted toact as Wheel stops f engaging the forward Wheels of the .car/to check forward movement thereof. This piatform has secured thereto a shaft operating in' bearings 25 carried 'by the frame, these bearings being so iocated that a cai', when disposed upon the platform and engagedvvith the Wheel stopsf, has its center cf gravit-y lying approximately 'vertically above this Shaft.

l Associated with this platform is bumper Y einber for limiting oscillation of the piatform 'with `the car thereonf liiiisk bumper Ymember vcomprises a 'Ushaped elementvr 26 straddling the platform at the forvvaid end i thereof and having'its legs guided by thek frame Y1'0 for-limited movement in the gen- 1 eral plane of the'member. This movement is resisted by a' cushioning Vdevice,isiicli'as a spring 27. The cross bar 28 of the U-shaped memberengages the car 171 .When the'platform istiltedva predetermined distanceand limits this tilting movement. I, f

Supported by the frame 10 is a suitable ycable reel 28L operated by a motor M or other suitable source of power. llliis cable reel is' controlled Afrom the' platform,y as indicated lat 29, andhas'vvound thereon Vvak cable 30 yeX- tendingto therear' of the traine beneath the frame and/at the rear o the traine, passing l I over'asheav'e `31 tothe "upper surface of the* traine-This cable'and thecarj 171 arek provided'with c'oactingfrneans for connecting` thev same and the level'ot this connection at, the
